Direct Configuration
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
NOTE
To carry out direct configuration, you require a direct configuration cable (order code "DPC"), the
LeoPC1 program (supplied with the cable) and the corresponding configuration files. After the program
has been installed, consult the online help utility for a description of the PC program and its setup.
Remote configuration
: For remote configuration, the CS2 password must be entered via the parameter "pass-
word DPC", otherwise the values can only be read and not written. If the unit is at the CS0 pass code level it will
only permit the user to read the parameters. The control unit will not permit the user to modify any of the para-
meters. When the CS2 pass code is entered via LeoPC1 through the CAN bus, configuration of the unit will only
be able to be performed through the CAN bus. The pass code level will change back to CS0 after 2 hours of inac-
tivity, at which point the pass code will have to be entered again to modify any parameters. The password must
be input prior to loading a language file. If the CS2 password is entered directly into the control unit, configura-
tion via the CAN bus is automatically enabled.
NOTE
The direct configuration via LeoPC1 and the configuration using the control panel are independent of
each other and must be unlocked independent of each other. Unlocking the access via the control pan-
el does not permit a configuration via LeoPC1 and the other way round.
CAUTION
If the following parameter "direct para." is configured to "YES", communication via the CAN bus (ter-
minals X1 to X5) is disabled. If communication is to be re-established via the CAN bus after the unit is
configured (e.g. CAN bus connection to a Gateway GW 4), "Direct para." must be set to "NO"!
Direct configuration is disabled once the firing speed has been reached. This means that if further mo-
fifications to the control unit's parameters is desired, the only possible methods to do this is using the
display and push buttons manually or via the CAN bus interface. The parameter "Direct para." is auto-
matically changed from YES to NO (this is a function of the control unit software). The direct configura-
tion function is de-activated for safety reasons. This is to prevent the possibility of a simultaneous ge-
nerator start up and closing of circuit breakers to a dead bus in a multiple generator system (e.g.
emergency power situation).
Parameter
10
Direct para.
YES
Direct configuration
YES/NO
YES
.............. The direct configuration plug is enabled and direct configuration of
the control is possible. The CAN bus terminals X1-X5 are disabled,
terminating any communication for the unit on the CAN bus. The
following conditions must be met in order to carry out configuration
via the direct configuration cable:
- A connection must be established via the direct configuration cable
between the unit and the PC
- The baud rate of the PC program must be set to 9,600 Baud
- The corresponding configuration file must be used (file name:
"xxxx-xxxx-yyy-zz.asm", initiated by xxxx-xxxx-yyy-zz.cfg)
NO
................ The configuration port is disabled and direct configuration cannot be
performed. The CAN bus connection via the terminals X1 to X5 is
enabled.
